HOLLOW TIL.

To all whom t may concern lle it known that'l., VILLIAM H. Bunn, acitizen of the lUnited States, and a resident of the city of St. vLouisand State of Mis.

souri, have invented a new and useful Improvement in Hollow Tiles, ofwhich the followingfis a specification. 4

My invention relates to hollow tiling for use in floors, walls and otherparts of structures, and consists in` anew and improved form of tile`unit adapted to be used with plastic material to' form animprovedstructure.

The objects of my invention are, to lighten the structure withoutsacrificing strength, to lessen the 'cost of construction by eliminatingm-uch expensive false work or centering and by enabling thewcrk to bedone by unskilled labor, and to make the structure damp and cold-proof.

My invention comprises a hollow tileunit formed in two sections so as tobe completely linclosed on all sides, and provided with lat-4 eralflanges. Such aunit is practically impervious to moisture, and is anexcellent non-conductor of heat, and may be used vfor floors, walls,ceilings, furring, ireproong and analogous uses in buildings, forpaving, for cisterns, wells, bulkheads, chimneys and similar masonrystructures. v

My invention further consists in the herein described novel arrangementof hollow tile units to form improved heat-insulating and moisture-proofbuilding or masonry structures.

My invention also comprises otherV improvements as more fullyhereinafter set forth in connection with the accompanying drawings, inwhich like numerals are used to designate like pants. throughout theseveral views,l and in'which- Figure 1 is'an isometric view of oneform,v

my improved tile illustrated in Figs. 1 andI 2. Fig. tis a 4partialplanview. of a Hoor panel embodying' my improved tile units with reinforcedconcrete placed in thespaces between adjacent units; Fig. 5 is a sectionon line 5--5 of Fig. 4, and Figl isa section on the lined-Gef' Fig. 4;

upper section 11, a lower section 12, and a y stiffening member 15,heldtogether by thin'- webs at 16. The stili'ening member may beomitted, andis not necessary with small tiles. -Such shape lends itself,readily to manufacture in a pug mill or tile forming machine ofordinarytype. `The webs are thin enough that the baked tile may becracked in pieces, the piece l5 being discarded. The pieces 11 and 12,when arranged atj right angles to each other as shown in Figa@J and thepart 11 brought down to embrace the part 12, form a hollow tile unitcompletely closed on all six sides. The sections 11 and 1Q are providedwith lateral flanges 13 and 14C, adapted to form a flange extendingsubstantially all the way around the lower edge of the assembled hollowtile unit as shown in Fig. 3. The form and arrangement of the tiles aresuch that in assembled relation the side walls of each tile making up aunit snugly embrace the web of the other tile of the same unit, therebyinterlocking and securing each other in assembled position.

When the tiles. are arranged in rows on flat surface `adjacent oneanother withf y anges in juxtaposition, square spaces at the corners ofthe tiles between the flanges are left unfilled, and. small flat tiles17 are placed therein in order to completely cover the surface on whichthe tiles rest. Plastic material may then be placed between the tiles,andsuch materia-l willneither penetrate to the interior of the tiles, aswould be the case if the sidesvwereperforated, nor will l it passthrough between the tiles onto the suplporting surface. Such tilesmay`be used 1n floor panels, for example, supported only on skeletoncentering, and concreteor other plastic, or binding materialv placed inthe spaces between the tiles over the flanges thereof, these vflangesand the small square tiles 17, serving to .supportthe plastic materialuntil such time as it shall harden suflif Vciently togive it strengthenough to carry the floor load, after which .time the centering may beremoved. As the extremities of Athe-'side `walls ofeach tile snuglyembrace thel web of the mating tile and are prevented `thereby frombeing thrust inward, the holv low units may be safely exposed to heavypressure on their exterior, suoli as is incidental to the placing andtamping of plastic concrete, for example, without danger of crackingott' their side walls. Much less lumber'tor centering need be used withmy improved tile units than with tiles not provided with means forsupporting the plastic material, vbut where the centering itself isrelied ou for this purpose.

Reinforcing rods may be inserted in the spaces between the units beforethe concrete is placed, and arranged to extend crosswise in bothdirect-ions through the panel from the margins thereof, thus providing atwoway reinforcement. Such an arrangement is shown in Figs. 4, 5 and 6,in which the hollow tiles formed by assembling the parts l1 and 12 toembrace each other are arranged with the flanges 13 in juxtapositionthroughout the panel in one direction and the anges 14 in juxtapositionin a direction at right angles thereto. Reinforcing rods 18 and 19 arepositioned near the bottoms of the spaces or channels thus formedbetween the tiles, and above the lateral flanges thereof, and thesespaces are then tilled with concrete. These o erations can all be per-Itormed by unskilled labor as there is no necessity for pointing thetile with mortar or cement as is necessary with the ordinary tile havingopenings therethrough, for there being no openings in the side walls ofthev tiles, the concrete can be poured into the intervening spaceswithout danger of filling up the hollow spaces within the tiles. Thelateral flanges 13 and 14; and lling tiles 17 provide an unbrokensurface upon which the concrete is supported without the use of theusual w ter tight forms. f

' The ollow tile being lighter than the ordinary' forms of tile, alighterv centering can be used to support it. The 'centering usedv withmy improved tile concrete construction may be made of strips of rough orlnotty lumber, the only requisite being that it shall present asubstantially uniform surface upon which the tile may be positioned. Thecontinuous smooth surface necessary when lconcrete is to 'be used withtile not having" the lateral ,flanges is unnecessary with m'y tile.

It is evident that my improved hollow tile unit can be used in otherways than those above shown and described, for exam le, in hollow wallso'r for furring, and I db not wish to limit myself to the precise formsof tile herein shown nor to the arrangement above described.

What I claim and desire to secure by Letters Patent is :l

1. A hollow tile unit composed of two tile sections comprising sideportions and a connecting web portlon, the distance between the oppositesides of each section being as great as the length ot' the 'sides andweb oi the 'other section, said sections being arranged with the sidesof each embracing the web of the other, whereby one section constitutesthe bottom'and two sides ofr the unit andthe other section constitutesthe top and the. two remaining` sides of said unit.

2. A hollow tile unit composed of two tile channel sections of equalheight, one of said sections being arranged to constitute the bottom andtwo sides of the unit and the other being arranged to constitute the topand two remaining sides of the unit, both the length and the distancebetween the opposite sides of the top section being equal to each otherand also being equal to the length and the distance between the oppositesides ofthe bottom section, said sections interlocking with their sidesstraddling the top and bottom of the unit.'

3. A11-open end box tile having its side walls scored midway betweenitsv top and bottom, the clear distance between said side walls being asgreat as the length of theV tile, and a bridge wall connecting said sidewalls at points adjacent to said scores.

4."An open end box tile having its side walls scored midway between itstop and bottom, the clear distance between said side walls being asgreat as the length of the tile, a bridge wall connecting said sidewalls at points adjacent. to said scores, and laterally extending'flanges on said sides along the lower edges thereof andV immediatelyabove said scores.

5. A' hollow unit composed of two tiles of equal height arranged withtheir axes transverse to yeach other, each tile comprising a web and twooppositely arranged side walls, the side walls of each tile being spacedapart a distance equal to the length of the other tile and arranged toembrace the webof the other tile.

6. A hollow unit for composite structures, said unit being composed oftwo U-shaped tiles, one of which is inverted and placed at right anglesto the other`between the upper edges of the side walls thereof, and thesidey walls of said inverted tile embracing the bottom of the other andterminating flush with the bottom surface of theunit.
